Abstract

The invention discloses a construction device and method for a shield tunnel.The construction device comprises a connecting ring plate, a steel sleeve, concrete pipe sheets arranged in the steel sleeve and a shield system.The connecting ring plate is pre-buried on a pit support structure.The shield system comprises a shield shell.The shield shell is arranged between the steel sleeve and the concrete pipe sheet.The end face of the steel sleeve and the connecting ring plate are fixedly connected.The space between the steel sleeve and the shield shell and the space between the shield shell and the concrete pipe sheets are both filled with clay shock for preventing water and oil loss.A plurality of grouting holes for injecting the clay shock are formed in the steel sleeve.According to the construction device and method, underground water and soil loss can be effectively sealed, the situation that soil disturbance is caused by water and soil loss, and consequently a shield originating accident is caused is avoided, and construction is convenient, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a construction device and a construction method of a shield tunnel. Background technique [0002] Excavating tunnels with shield machines is a method of tunnel design and construction, which is widely used in our country. The shield machine generally starts from the open-cut foundation pit, enters the ground to excavate and construct the tunnel lining structure at the same time, and finally reaches the open-cut foundation pit at the other end of the tunnel to form a through tunnel. During the process of the shield machine cutting the foundation pit enclosure structure into the soil (hereinafter referred to as "shield tunnel initiation") in the open excavation pit, the stratum is exposed and disturbed, and the groundwater begins to lose, which can easily cause landslide accidents, and cause The underground pipe network and surrounding buildings are damaged...
